The reason for the driver's side air conditioning not being cool while the passenger side is cool is due to issues with the switch in the air ducts and blockages in the air ducts or dirty air conditioning pipelines. Car air conditioning should be turned on regularly, regardless of need, at least once a week. Issues with the switch in the air ducts: If the driver's side air conditioning is not cool while the passenger side is cool, it indicates that cold air is not circulating properly. Try switching between the internal and external air circulation modes a few times. Running the air conditioning while keeping the external circulation on continuously will draw hot air from outside into the car, naturally reducing the cooling effect of the air conditioning. Therefore, in hot weather, after using the external circulation for ventilation, switch back to internal circulation as soon as possible. However, do not keep the internal circulation on all the time, as prolonged lack of air circulation inside the car can lead to carbon monoxide poisoning. The best approach is to alternate between internal and external circulation. Blockages in the air ducts or dirty air conditioning pipelines: Turn the fan to its maximum setting and check the airflow at the vents with your hand. If the airflow is noticeably weaker than before, it is likely that the air ducts are blocked. The car's air conditioning system has an air filter, usually located behind the glove box on the passenger side (though there are exceptions, such as above the accelerator and brake pedals). If the air conditioning filter is too dirty, it should be replaced as soon as possible. Generally, a filter used for a year needs to be replaced. If the filter is not too dirty or if the airflow remains weak after replacement, specialized maintenance personnel should be consulted to clean the air conditioning pipelines and air ducts.
